We have previously shown that chronic exposure to ambient fine particulate matter (less than 2.5 μm in aerodynamic diameter, PM₂.₅) pollution in conjunction with high-fat diet induces insulin resistance through alterations in inflammatory pathways. In this study, we evaluated the effects of PM₂.₅ exposure over a substantive duration of a rodent's lifespan and focused on the impact of long-term ...

Alginite has been evaluated as an efficient pollution control material. In this paper, alginite from maar Pinciná (SR) for removal of Cd ions from aqueous solution was studied. The potential sorbent was characterized by X-ray fluorescence analysis (RFA) analysis, Fourier transform infrared spectral analysis (FT-IR) and specific surface area (SSA) was also determined. The sorption process was op...

Pollution has become a very serious threat to our environment. Monitoring pollution is the rst step toward planning to save the environment. The use of dierential equations, monitoring pollution has become possible. In this paper, a Ritz-collocation method is introduced to solve non-linear oscillatory systems such as modelling the pollution of a system of lakes. The method is based upon Bernoul...

{ 15 { codewords. If any of the strings supplied by P k fails a multilinearity test, then V accepts P 3?k 's claim about whether or not w 2 L. It remains to show how V can test equality of two functions that are both 1=4-close to multilinear polynomials in K n X 1 ; : : :; X n ]. This can also be done using a well-known fact about polynomials. Schwartz's Lemma Sc80]: Two distinct polynomials in...

Nanostructured materials have wide range of applications due to their interesting size-dependent chemical and physical properties compared to particles of size in the range of micrometer. Copper oxide nano materials are of interest on account of their potential uses in many technological fields. In this study CuO nanoparticles were synthesized via simple sol gel method using basic CuSO4 as wet ...

background: glioma is the most common primary brain tumor with poor prognosis. temozolomide (tmz) has been used with irradiation (ir) to treat gliomas. the aim of the present study was to evaluate the cytotoxic and radiosensitizing effect of tmz when combined with high-dose and high-dose rate of gamma irradiation in vitro. methods: two ‘u87mg’ cell lines and skin fibroblast were cultured and as...

To test directly the determinant selection hypothesis of immune response gene function, we primed strain 13 T lymphocytes in vitro with allogeneic bovine insulin pulsed strain 2 macrophages. Strain 2 macrophages were found to be fully competent to present bovine insulin B chain to strain 13 T cells despite the fact that strain 2 guinea pigs are normally totally unresponsive to this antigen. The...
